多作业共用打印机控制
我们有 4 台打印机,在一个池中配置了相同的纸盘/纸张。 可以提交多个作业,并且它会以循环方式将作业发送到空闲的打印机。 这很好用,但是……我们正在开发一个基于 Web 的新应用程序,可以生成 PDF 输出文件。 一组数据可能涉及在3个不同的托盘上输出的3个不同的打印“作业”,但优选地一旦完成即可仅从一台打印机上拾取。 有什么建议如何发送 3 个打印“作业”,但让该“组”作业全部排队到一台物理打印机上吗? 目前,第 3 方假脱机程序已就位,它很旧,有点蹩脚,我希望用 Windows 打印机池或其他第 3 方应用程序替换它(如果您可以建议一个可以提供所需控制的应用程序)。
谢谢。
We've got 4 printers with identical trays/paper configured in a pool. Multiple jobs can be submitted and it will kind of round-robin send the jobs to the printers per whichever one is idle. That works good, but.. We're working on a new application that is web-based and produces PDF output files. A "set" of data might involve 3 different print "jobs" coming out on 3 different trays but would preferably be available to pickup once complete off of only one of the printers. Any suggestions how to send 3 print "jobs" but have that "set" of jobs all be queued up to only one physical printer? Currently a 3rd party spooler is in place, it's old, it's kind of crappy, I'm looking to replace this with Windows printer pooling or some other 3rd party app if you can suggest one that would offer the needed control.
Thanks.

最好的方法是在将 PDF 文件发送到打印机之前合并它们。 这将允许在单个打印作业中发送“一组”PDF 文件,并确保将它们发送到单个打印机。 这将与 Windows 打印机池兼容,并且无需第 3 方后台打印程序应用程序即可工作。
合并 PDF 文件的一种方法是使用免费的 PDFTK 命令行工具包,网址为:

cat 命令可用于组合将 PDF 文件转换为单个 PDF 以供打印作业“设置”:
The best way to do this would be to combine the PDF files before sending them to the printer. This would allow the "set" of PDF files to be sent in a single print job, and would ensure that they are sent to a single printer. This would be compatible with Windows printer pooling, and would work without a 3rd party spooler app.
One way to combine the PDF files is to use the free PDFTK command line toolkit available at:

The cat command can be used to combine the PDF files into a single PDF for the print job "set":
